This invention relates to improvements in the art of `anchorage especially to inaccessible or diiiculty accessible work, and has as its primary object the combining of facility with effectiveness of anchorage.

A. further object is provision for adjustment and variability of relative location of the anchorage. l

More specifically, the invention comprehends means of purchase for an anchorage element, which means of purchase is adapted for relative variability of position- Without l dislocation to an inoperative condition.

Among the further objects of the present invention is the anchorage of means of purchase from the accessible side of a Wall or like work to the inaccessible side thereof.

Also, a still further' object in view is the ready, easy, and 'effective introduction of such means of purchase to the inaccessible sideof. work from the accessible side thereof in a manner to cause anchorage of the means of purchase of such form as to permit variable accessibility.

With these and other objects in view, as will in part hereinafter be stated and in part become apparent,` the invention comprises certain nevel constructions', combinations,

and arrangements of partsas will hereinafter f become apparent and be subsequently pointed out in the appended claims.

In various industrial arts, such asauto- 70 lmobile body construction, cornice work, ven'- tilation ducts, and other sheet metal and like wall construction,.it frequently occurs that anchora e must be had to a wall whose inner surface 1s either wholly inaccessible or' acces- 75 sible only1 with diiiiculty, and, in such inere,may be used some form of anchorage device such as the types covered by my severalUnited States Letters Patent numbered and dated respectively: 1,299,232, dated AprilA 1, 19.19; 1,411,184, dated March 28, 1922; 1,465,148, dated August 14, 1923; 1,482,151, dated January 29, 1924;'1,485,202 Dated February 26, 41924; 1,526,182, ydatei February 10, 1925; 1,545,471, dated July 7, .1925.V- 1 e Suchfanchorage devices are especially effective for this class of work, but it sometimes occurs that a further diiliculty arises from the fact that a sheet, strip, or other 00 part or wall is to be anchored to another sheet, strip, wall, or other work having an inaccessible or inner surface, and that definite spacing ofthe anchorage'screw or pin in the superposed or exterior work isA required. Even with the most careful templets, it is not always practicable to have apertures formed .in the inner and outer pieces of work which register with precision, as, for exam le, when applying molding to the casing o a window frame in an automobile body structure. In such instances the anchorage pin or screw, when passed through a previously formed aperture in the mold- .ing or superposed work, may miss the aperture in the inner wall just enough to prevent making the needed connection or may just engage at the tip in a manner to cause the screw or anchorage pin to cant inapproachingfthe seated position. It becomes desirable in such instances, therefore, to`provide some means of purchase to the inner wall which is susceptible of at` ,least a slight amount of floating movement or relative adjustability, so that an approaching entering -tip ofa fastening screw or pin will cause the purchase means to shift or float toa proper alinement and enable the production of an effective anchorage' even when the pin or screw receiving apertures would not otherwise accurately register.

In such cases, attempts have been made to provide supplemental anchorage means, but so far as known to me, such attempts have not been successful for various reasons. One of such reasons lies in the difficulty of retaining a supplemental anchorage means or purchase means in place while leaving it free to float pending application of the anchoring screw or pin. The present invention overcomes all these difficulties and provides for successful anchorage including engagement with the inaccessible or inner face of the main or inner wall and at the same time provides a floating purchase means capable of such variations in location as may be required in practice.

For the detailed understanding of the invention, reference is had to the accompanying drawing, in which l indicates the anchorage plate of the improved purchase means. Plate 1 engages the inner face of a Wall or work 2. Plate 1 is apertured at 3 to receive an anchoring screw 4. .Extending laterally from the middle areas of the edges of plate 1 are wings, each bent at 6, 6, to provide an offset the thickness of wall 2, and each terminating in a foot 7 beyond the offset 6 to overlie wall 2 while plate 1 underlies said Awall when the parts are assembled.

i Wall 2 is formed with an aperture 8 of a Width corresponding to the width of plate 1 to permit snug passage of the plate through the aperture, but sometimes aperture 8 will be slightly wider and permit lateral play and result in the final assemblage of FigureV 8, as hereinafter mentioned. Aperture 8 is of a length subst-antially equal to the length of that part of plate 1 from one end thereedges of -the t 1 with work, one end of plate 1 is inserted through aperture 8 and moved to a position underlapping wa1l2 as much as possible, and then plate 1 is moved through .aperture 8 with a swinging face-wise movement to the position seen in Figure 6. Feet 7 remain at the outer face of wall 2, and plate 1 is' slid back until there is less underlap at the left end, as seen in Figure 6, and some underlap of wall 2 at the righthand end of aperture 8. When thus centered, plate 1 is in the position seen in Figure 7 and is ready to receive Athe anchoring screw 4 in the aperture 3. The

assemblage to the condition of Figures 4 and 5 is accomplished after the centering of plate 1, by merely applying the strip, plate or other work 10 face-wise to wall 2 and inserting screw 4 through an aperture 9 in work 10' and into aperture 3, and threading the screw to a seated position firmly and effectively clamping the parts together.

It will thus be seem-that plate 1 is located for effective anchorage to the inaccessible inner surface of wall 2 by approaching the wall from the exterior, and if the plate 1 remains centered, the final location will be as seen in Figure 7; but, if aperture 8 in any given case should be slightly wider than the width of plate 1, (as it is likely to be in many cases to facilitate ease of assemblage) the plate 1 is liable to assume the skewed position of Figure 8, which, of course, is immaterial because plate l is never seen after application, and the anchorage will be just as effective when skewed as when otherwise. Also, under some conditions, variation of the location of aperture 8 may result in location of plate 1 as seen' in Figure 6, with all the underlap at one end of aperture 8. This also will not prevent an effective anchorage, as plate 1 cannot possibly escape through aperture Sunless rocked or swung, which movement is not possible so long as screw 4 and part 10 remain in place. Of course, aperture 8 may be formed in a perfectly flat wall 2, or an offset 11 may be provided to accommodate the feet 7, as seen in Figures 9 and 10. 4It is important that the feet 7 extend substantially'at right angles to the main body or plate 1, .so that the parts will effectivelyfcooperate wlth ajproperly proportioned opening 8 in the wall, as above indicated. i

There is a very substantial advantage provided in the present invention from the fact that the purchase-affording means are designed to be applied easily and quickly from the exterior and to remain in place indefinite- 1y before being used. Multiple assemblage is thus facilitated.

Plate 1 is an anchorage-means receiver, in the sense of affording the needed purchase for 5 the anchoring screw, and while said plate becomes in fact a nut or the equivalent thereof during use, it is of course obvious that other anchorage means and other forms of provision for purchase may be provided within the scope of the invention.

The invention of this application is distinguished from the subject matter of my copending applications, Serial Nos. 75,830 and 75,831, led December 16, 1925, in that said co-pending applications disclose structures wherein no ioating of the anchorage receiving means `is provided for. It should be understood from reference to my above-identified patents that the screw 4 has its threads hardened siciently for entering metal such as soft iron or soft steel, substantially without injury to the threads, so that the entering ofthe purchase means is eiectedwith great facility.

This application is a division of my coending application Serial No. 253,755, filed gebruary 11, 1928 and issued Aug-4, 1931, as Patent No. 1,817 ,584.
